noun, Physics. 1. a theory that the particles in a gas move freely and rapidly along straight lines but often collide, resulting in variations in their velocity and direction. Pressure is interpreted as arising from the impacts of these particles with the walls of a container.
noun, Physics. 1. a theory that the temperature of a body is determined by the average kinetic energy of its particles and that an inflow of heat increases this energy.
